trigger='/' not working

[lawrencenika]

Steps to reproduce:

1. try

    <Mention
        trigger='\/'
        markup='\/[__display__](__id__)'

2. try

    <Mention
        trigger='/'
        markup='/[__display__](__id__)'

Expected behaviour:
tried : trigger like below, work without any issue.

    <Mention
        trigger=':'
        markup=':[__display__](__id__)'

Observed behaviour:
when typing /abc, no data list is shown. When remove markup and only uses trigger='/' I have to type something after / to trigger the dat list, if not nothing is shown.

Workaround:
